Inventor: MARKELJ Z
IPC: B23K9/028
Filed: 1987-04-01
Abstract: Process and corresponding apparatus, in the form of a swing frame for centring and securing the plate-shaped head (101) during repairs to mis-shapen rim drillings. The process involves making circular cutouts in the crown of the straight section (102) of the plate-shaped head, carrying out peripheral conical shaping on both sides and making the new crown plate (109). The rim is then centred and secured by support elements (13) to the swing frame by means of a conical pusher (27) clamped to the thread shoulder (2). The new crown plate is secured between the section support and the plate-shaped pusher before welding. Said support and pusher are height-adjusted on the thread shoulder. The rim is centred and clamped in a tilted position to the frame with a shortened thread shoulder. End welding, grinding to tolerances, making of holes and conical hole reaming may be carried out on the tilted frame or on the shortened thread shoulder frame, according to the rim position. In the positions envisaged, the rim is always secured centrally, the rim repair thus allowing the same properties to be achieved as in a new, industrially produced rim.

A control circuit (ASA) for the switching transistor has a fixed frequent, astable multivibrator (V121, V130), and an output signal from the multivibrator is fed to the input of a controlled power source (V140, V143, R140) via an isolating transformer (V131). The output of the power source is connected to the control electrode of the switching transistor (V160) in the primary circuit in order to join the latter to the first flank of the multivibrator output signal. The control electrode of the switching transistor can be connected to a tripping potential via a controlled thyristor (V142, V141). The actuating signal (Us') and the output signal (UI) of the current sensor (R161) are fed to the thyristor in the form of a control signal and the respective second flanks of the multivibrator output signal are supplied to the thyristor as turn-off pulses.

Abstract: Method and apparatus for contacting particulate solid matter with a fluid in a pressure vessel (10) through which the fluid continuously moves at high, supercritical, pressure while the particulate solid matter is periodically moved via isolatable pressurizable vessels (12,16) which are periodically pressurized and depressurized to and from the supercritical pressure to facilitate periodic movement of the particulate solids between the pressure vessel and the isolatable pressurizable vessels. A supply of the fluid is maintained at an intermediate pressure at which the fluid exists in both the liquid and gaseous states. The pressurizable vessels are raised to supercritical pressure by first using intermediate pressure fluid in the gaseous state and then in the liquid state, followed by introducing fluid at the supercritical pressure. The vessels are depressurized by first venting and then pumping to the intermediate pressure fluid supply.

Abstract: A process for the production of a stabilized rosin and a stabilized rosin obtainable by the process. According to the process rosin is heated in the presence of a phosphoric acid or a strong acid in combination with a phosphate containing substance and disproportionated by addition of iodine. Preferably the rosin is first heated in the presence of the phosphoric acid or the strong acid in combination with the phosphate containing substance and thereafter disproportionated by the addition of iodine. Iodine is preferably added in at least two steps and the disproportionation is allowed to proceed between each step. The stabilized rosin can be used as a tackifier resin in adhesives and as a sizing agent for paper, paper boards and similar products.
